The guy who never gets the girl; he who finishes last; thou who art nice shall get screwed; Anyone who goes out of their way to help someone and gets screwed for it; the guy who likes the girl listens to her after the break-up and then is forgotten until she is dumped again.

Example of The Nice Guy rule in action: In England, there was a bank robbery and the robber couldn't open the front door, because his hands were full of money, an innocent bystander is walking by and sees the man struggling with the door and holds it open for him, that man was arrested for assisting an armed robbery.
